Abstract
With the continuous development of the logistics industry, forklift trucks, as essential handling equipment, play an important role. In recent years, the sales volume of forklifts has increased dramatically, and the manufacturers of forklifts have developed more rapidly. Besides having high energy sales, modern forklifts also have to consider safety. The forklift seat is the most contact between the driver and the truck. Road factors cause the vibration of the forklift truck, and the operation process is reduced by the seat, which improves the safety and driving conditions for the driver. Based on ergonomics, this paper analyzes the working environment of the forklift seat, puts forward the design goal of the seat, and extracts the design method to improve the safety and comfort of the forklift seat based on ergonomics theory: the seat comfort position, shape, size and other comprehensive design research. According to the data on adult human body size provided by GBl0000-88 and the ergonomics principle of seat design, the relationship between seat parameters and human body size data is studied. A forklift seat size data suitable for the The seat's comfort (H point) position range is calculated using Matlab software. Based on the ergonomics design module of CATIA, this paper evaluates the comfort of the forklift seat, and the results show that each part meets the comfort requirements of the forklift seat. ADAMS/View simplifies the seat frame structure, the shock absorber model is established, the drive is created using the SWEEP function, and the virtual prototype model is established. The related transfer characteristic curves are obtained according to the dynamic simulation of the seat frame with different load weights. The results show that the increase of spring stiffness shows a linear increase. It is shown that increasing the damping coefficient of the spring can effectively enhance vibration reduction. This conclusion is also verified by driving the vibration test of the forklift seat.
